Brooklyn fellas will make you a suit custom. Says "designed" in ny so I wonder if they are getting the shipping from china. The prices are much higher as there is no website automation…

And custom suits online – lotsa good education and customization.

even more customization.
they have lots of fabrics and include a lot of info about the fabrics/styles/assembly and how to take measurements.

Wide style of customizing options – essentially what you would get with a tailor, just a smaller selection of fabrics.
Nice wizard to visualize the shirt as you make it. Actual sewing takes place in shanghai.
